FIELD: engines and pumps.
SUBSTANCE: invention relates to cooling of electronic components, particularly, those of gearboxes. Proposed method is based on cooling of electronic unit (20) arranged in hardware chamber (11) located inside the housing of gearbox (1) by coolant flow circulating through water jacket. At the same time said coolant jets are measured by turbine connected with pulse magnetic transducer. Besides, temperature transducer measures coolant temperature. When coolant does not flow through water jacket and/or coolant temperature exceeds preset threshold signalling system is switched on and/or electronic unit (20) is switched off.
EFFECT: higher reliability.
